A 45-year-old woman developed fatigue in July and had blood counts that were reported to be normal. She was hospitalized because of a very severe headache in December, and was found to have a blood pressure of 175/90. Her laboratory values were as follows: hemoglobin (8.3 g/dL), RBC count (2.2 × 10^6/μl), Hct (23%), MCV (89 fL), WBCs (5100/μl), platelets (262 × 10^3/μl), and reticulocyte count 0.8%. What is the diagnosis for this patient?
